Remaining battery charge is now accurately detected for Rechargeable Li-ion Battery EN-EL14a.With A firmware Ver. 1.01/B firmware Ver. 1.01 or earlier, the number of images that can be captured (battery life) when an EN-EL14a is used is less than when an EN-EL14 is used. By upgrading A firmware to Ver. 1.02 and B firmware to Ver. 1.01, EN-EL14a performance is maximized so that more images can be captured (battery life) than when an EN-EL14 is used.
